<h4 id="扩展ASCII打印字符"><a href="#扩展ASCII打印字符" class="headerlink" title="扩展ASCII打印字符"></a>扩展ASCII打印字符</h4><p>扩展的ASCII字符满足了对更多字符的需求。扩展的ASCII包含ASCII中已有的128个字符（数字0–32显示在</p>
<p>下图中），又增加了128个字符，总共是256个。即使有了这些更多的字符，许多语言还是包含无法压缩到</p>
<p>256个字符中的符号。因此，出现了一些ASCII的变体来囊括地区性字符和符号。例如，许多软件程序把</p>
<p>ASCII表（又称作ISO8859-1）用于北美、西欧、澳大利亚和非洲的语言。</p>
